Types of Urological Supplies: A Complete Guide to Catheters and Drainage Bags

Managing a urological condition can feel overwhelming, especially when you're faced with a wide range of products and medical terminology you may not be familiar with. Whether you're newly diagnosed with urinary retention, recovering from surgery, or supporting a loved one with a neurogenic bladder, understanding the different types of urological supplies available is the first step toward confident, comfortable care.

In this guide, we break down the most common urological products — what they are, who they're for, and how to choose the right one for your needs.

1. Intermittent Catheters

Intermittent catheters are single-use catheters inserted into the urethra to drain the bladder and then removed. They are used several times throughout the day — typically every 4 to 6 hours — and are the most commonly recommended catheter type for individuals who can self-catheterize.

There are three main types of intermittent catheters:

• Standard (uncoated) catheters — require a separate lubricant before insertion and are the most affordable option.
• Hydrophilic-coated catheters — pre-lubricated with a water-activated coating for smoother, more comfortable insertion and a lower risk of urinary tract infections (UTIs).
• Coude tip catheters — feature a curved tip to navigate around an enlarged prostate or urethral stricture, primarily used by men who experience difficulty with standard insertion.

Intermittent catheters are ideal for individuals with urinary retention, neurogenic bladder (from spinal cord injury, MS, or spina bifida), or post-surgical bladder dysfunction. Browse our full selection of intermittent catheters to find the right type and size for your needs.

2. Closed System Catheter Kits

For individuals who are prone to recurrent UTIs or who catheterize in non-sterile environments, closed system catheter kits offer the highest level of infection protection available. These all-in-one kits include a pre-lubricated catheter, a pre-attached sterile collection bag, and a protective introducer tip that shields the catheter from contamination during insertion — creating a completely no-touch catheterization experience.

Clinical research supports the use of closed system catheters as an effective strategy for reducing catheter-associated urinary tract infections (CAUTIs), making them the preferred choice for spinal cord injury patients, immunocompromised individuals, and anyone who catheterizes away from home.

3. Indwelling Foley Catheters

Unlike intermittent catheters, an indwelling Foley catheter is designed to remain in the bladder for an extended period — typically 4 to 6 weeks — held in place by a small inflatable balloon. Urine drains continuously through the catheter into a connected drainage bag.

Foley catheters are available in latex and 100% silicone (latex-free) materials, and in 2-way (standard drainage) and 3-way (continuous bladder irrigation) configurations. They are commonly used for patients with severe urinary retention, those who cannot self-catheterize, individuals in palliative care, and post-operative patients requiring continuous urine output monitoring.

Silicone Foley catheters are recommended for long-term use due to their biocompatibility and reduced risk of encrustation. Shop our range of indwelling Foley catheters in multiple French sizes and materials.

4. External Catheters (Condom Catheters)

For men who experience urinary incontinence but do not require internal catheterization, external catheters — also called condom catheters — offer a non-invasive, comfortable alternative. The catheter fits over the penis like a condom and connects via tubing to a drainage bag, allowing urine to flow freely without any urethral insertion.

External catheters are available in self-adhesive and non-adhesive styles, and in latex and silicone (latex-free) materials. They are replaced daily and are particularly beneficial for men managing post-prostatectomy incontinence, neurogenic bladder, or mobility-related incontinence. Browse our external catheters in a range of sizes for a secure, leak-free fit.

5. Leg Drainage Bags

Whether you use an indwelling Foley catheter or an external catheter, a leg drainage bag is an essential accessory for daytime urine collection. Leg bags strap securely to the thigh or calf, hold between 500 mL and 1,000 mL of urine, and are designed to be worn discreetly under everyday clothing.

Key features to look for include an easy-to-operate drainage valve, an anti-reflux valve to prevent backflow, adjustable leg straps for comfort, and latex-free materials for sensitive skin. For nighttime use, most catheter users switch to a larger bedside overnight bag that holds up to 2,000 mL. Shop our selection of leg drainage bags for daytime and overnight options.

Choosing the Right Urological Supply

The right urological product depends on several factors, including your diagnosis, level of mobility, catheterization frequency, infection history, and personal preference. Here's a quick reference guide:

• Can self-catheterize, no recurrent UTIs — Standard or hydrophilic intermittent catheter
• Can self-catheterize, history of recurrent UTIs — Closed system catheter kit
• Cannot self-catheterize or requires continuous drainage — Indwelling Foley catheter
• Male with urinary incontinence, no retention — External (condom) catheter
• Need daytime urine collection with a catheter — Leg drainage bag

Always consult your urologist, continence nurse, or healthcare provider before switching catheter types or sizes. They can help you identify the safest and most comfortable option based on your specific medical history.

Complete Your Urological Care Routine

Urological supplies work best as part of a complete care routine. Pair your catheter and drainage bag with incontinence wipes and cleansing cloths for proper hygiene during catheter changes, and underpads and bed pads to protect surfaces from accidental leaks.

For individuals managing both catheter use and urinary incontinence, our full range of incontinence products — including briefs, pull-up underwear, pads, and guards — provides additional protection and peace of mind.
